Thrown Parts for a Vase

Okay so,
I am going to demonstrate how to make a vase
from parts. So the base that I’m going to do
is made from three sections. This is a vase
that’s made from a single piece of clay. Some things that you’ll notice
when you compare, is that the vase
that’s made in sections, well there’s a potential
for you to have more exaggeration in the form. Also,
size. Like if this is the largest
I’m able to throw, if I were to make a vase
from three sections, it could be this big
or bigger. I mean, you’re not really limited
to the number of sections that you throw
to assemble and create a vase. The body was thrown
as a closed form and then
a cylindrical top. And then this is just
a bowl thrown this way and then turned upside down
to attach to here. All right? You can
break the… Like if this
is too difficult to, this body is too difficult
to throw, you could always throw a bowl
and then another bowl that are joined
rim to rim. Okay. I have some parts over here
that were thrown yesterday that I’ll
just show. As you see
you probably have no… You probably
have a hard time figuring out what the vase
is going to look like. Actually these parts
were thrown this way. So that’s one of the challenges
with making a vase from parts is that the whole proportion
and figuring out what it’s all going to look like
in the end when it’s
put together, it’s very,
very tricky. So that’s one challenge
that you don’t really have to deal with when you make a vase
from a single piece of clay. One of the things that’s essential
with throwing with sections and this is also true
with making jars with lids, is that the parts
need to fit each
other. So when
I threw this I always start
with the body and then I measure
the base. Okay
and I want to make sure
that this measurement corresponds to this area
here because this bowl
is going to be flipped over. It’s going to be
attached. Okay. This being a closed form
I’ve got… I don’t have to worry about
how big this opening is for this
to sit on. If this wasn’t closed
then that would be more of an issue. Where parts come together,
you want to make sure that that you do your measurements
properly so that one part’s not falling
into the other. And say, for instance,
if I did want to make another part that would have been attached
to this, I’d want to make sure
I measured out here and that the base of the other piece
is that same measurement so they can stack
on top of each other. I’ve had students where they did
the measurements incorrectly and they measured
the inside of this and so then the other piece falls
inside of here. Make sure
that where you’re going
to attach that there’s plenty of surface area
for the joints so I would have made sure
that this lip was thicker and flat so that that other piece
has a nice surface to stack on to. Okay so those
are some considerations. So probably understand now
that planning is going to be
essential when you’re making a vase
from sections. Okay. So, I’m going to talk about
a couple of things while I set up. When I’m making a pot
that’s going to be made from parts, whether it’s a vase
or a jar, and I need the various parts
to fit well, I want to make sure
that the clay that I’m using for all
the parts came from
the same chunk. You want
to avoid situations where you’re having to use clay
from two different bags because the water content
might be a little bit different between the bags
of clay and that’s going to
affect shrinkage which in turn
will affect fit, the fit
of the different components. Okay. Always start off
with throwing the body. And the reason being
is that it’s
proportion. If I have the body
then I can refer to the body as I determine the size
that I want the other parts to be. [ Whirring noise ] I’m going to have to
throw this quickly because I need
to keep the video short. Even if I’m not planning
on keeping the floor to a pot, I still like to throw
with the floor intact. I can always
remove the floor later. Massive
air bubbles. And it’s
just going to make throwing
a bit more of a challenge. Well students like to see me
mess up so
[ snickers ] you might be in
for a treat. Let’s see. Okay. So I’m shaping
the body. Collaring. My throwing
tends to be very tight, very
precise. And I guess throwing
with air pockets and being
in a rush… is a good thing
if I’m trying to make very loose
looking pots. I’m going to make sure
I get the air, excuse me, the water and slip
out of this before
it’s too late. Okay. So this
is a closed form that
I’m throwing. Let’s get this as narrow an opening
as possible. Okay and there’s a very,
very small hole. It’s not completely
closed. And what this allows me
to do is I can exaggerate the shoulder
if I want it to be more shallow and if it feels like it’s about to
collapse on me, I can just pinch
that top off and close
the air off and then it allows me
to work on shaping. So I can have
a really shallow shoulder like this and it’s not going
to collapse. This
little balloon. All right. So that
is the closed form. You don’t have to throw
a closed form to make a vase
in sections. I just thought I’d show you
how to throw a more advanced form for those that want
that extra challenge. All right
and then what I’ll do
is I’ll just put a little hole. And you can do it there
or on the side, you know, a place that’s going to be
waste material anyway. And the reason why
that’s important to do is as the clay dries
it shrinks. If you have air
that can’t be vented out, the air pressure’s going to build up
as the clay shrinks and it’s going to cause
the wall to crack, split open
somewhere. Okay so
that’s the closed form. Ooops. Forgot to do
one thing. And I want to use the calipers
to measure the base. So the distance from here to here
is the same as this. And so
I’ll measure across. And there’s some extra thickness
down there that I’ll be able to trim away,
but still, I’ll take
this measurement. And I want the base that I create
to be that measurement. All right. So that’s loose
but I’m just going to deal with it anyway. I recommend,
beginning students, that you get
a good fit with the bat
on the wheel. Otherwise… Wow,
look at those air pockets. I don’t know
how that happened. Maybe it was a piece of clay
I had wedged. Okay. So throw
a bowl. Calipers
to make some measurements. The form
can get quite complicated quickly when you’re making a pot
in sections. So I try to keep the components
rather understated because if they’re quite
interesting pieces unto themselves then when you
combine them you might get a vase
that’s way too busy. So that’s
an aesthetic decision. All right,
so that is the base. I would have
done… used the calipers a little bit more
to keep checking the diameter of the very, very bottom
of the bowl, but I am limited by time on my computer
for this video. And I still have
a third section to throw. And because
it’s a closed form, I don’t have to really make
any measurements of the top. What I want to do
is consider what I want the top
to look like. Okay so,
make some sort of shape, whether it’s a cylinder
or cup, only
up to you. Okay but it should make sense
on the pot. Like if the surface is rather smooth
on the body, should it be smooth
on the neck as well? Okay. So think about
those kinds of things. There will be
another video where I’ll assemble
the various components. But this is
more or less done. Again with the water,
inside, outside, and then using the wire
to cut the pot free.
